Scare gas grenade
Scare gas grenades, or Scare grenades, produce a form of non-persistent nerve gas. The effects generated are the psychological and physical symptoms of anxiety. Scare gas can be absorbed through the skin and is rapid-acting, and therefore highly dangerous. It dissipates in ordinary atmospheres just as rapidly, however.
Typical battlefield reactions to being hit by Scare grenades include unwillingness to move or to fire one's weapon and even the refusal of direct orders. The need to escape danger can result in troops completely retreating.
